Be provided with next door 43 on the top of pressurized vessel 13, form a plurality of apertures 44 in the next door 43.Next door 43 marks off upper space 14 that is supplied to aqueous sodium hypochlorite solution and the principal space 45 that is supplied to carbon dioxide gas by gas duct 24.The below work of explanation sterilization water generating device.
The work overview of the sterilization water generating device of the 1st embodiment is described, by in the pressurized vessel 13 of the carbon dioxide gas of the pressure that has been full of specialized range, scattering the aqueous sodium hypochlorite solution that is adjusted to normality, carbon dioxide gas is dissolved in the aqueous sodium hypochlorite solution.Can be by the spread state of aqueous sodium hypochlorite solution, just the micronize degree of aqueous sodium hypochlorite solution is the size of surface-area, adjusts the dissolution degree of carbon dioxide gas.For example, will carry out micronized situation relatively with using spray nozzle, and utilize spray nozzle to carry out micronized mode and dissolve more carbon dioxide gas as dashing the situation of drenching ground distribution aqueous sodium hypochlorite solution.In addition, the situation that the situation that the pressure in the pressurized vessel 13 is set is highly set lowly, dissolving more carbon dioxide gas.These contents are for the design item, even carbon dioxide gas is dissolved to saturated level, Soda Ash Light 99.2min. can not make the sterilization water in the pressurized vessel 13 enter into the strongly-acid scope yet.
Ready mode
(1) valve 20 that will be relevant with the supply of carbon dioxide gas and the valve 39 that links to each other with sterilization water dispatch tube 37 are all closed.In addition, (2) valve 35 that will link to each other with the 1st pipe arrangement and the valve 40 that links to each other with water shoot 38 are all opened.Then, aqueous sodium hypochlorite solution is supplied to upper space 14, this clorox is injected into the principal space 45 by aperture 44 by brute force.The current of the clorox that sprays from a plurality of apertures 44 are collided mutually, and this helps micronize.
Dilute the flow of the former water of aqueous sodium hypochlorite solution by under meter 5 instrumentations, according to this flow, utilizing pump 8 that the aqueous sodium hypochlorite solution in the head tank 7 is sent to addition portion 10 mixes with former water, to obtain the aqueous sodium hypochlorite solution of normality, afterwards, the aqueous sodium hypochlorite solution that will be adjusted to the normality that meets application target by raw material supplying pipe 12 is supplied to pressurized vessel 13.
Because the rising pipe 31 that is connected in the bottom with pressurized vessel 13 is provided with throttling orifice plate 42, therefore accept the water level rising of pressurized vessel 13 of the supply of aqueous sodium hypochlorite solution.Be accompanied by the rising of water level, the air admission in the pressurized vessel 13 by branching portion the 23, the 1st pipe arrangement the 33, the 2nd pipe arrangement 34, water shoot 38, is discharged to the outside to gas duct 24.
Because the rising float 25 of water level rises, and detects water level in case be positioned at the limit switch 30 of uppermost position in fig-ure, then closes with the valve 35 that the air in the pressurized vessel 13 is expelled to the 1st outside relevant pipe arrangement 33.On the other hand, the valve 20 relevant with the supply of carbon dioxide gas opened, used 2 reducing valve, 18, the 19 post-decompression relatively carbon dioxide gass of low pressure, be supplied to pressurized vessel 13 by gas duct 24 from dioxide bottle 15.This control is undertaken by scheming outer controller.
In addition, in ready mode, for the air in the pressurized vessel 13 are expelled to the outside, can be at the top of pressurized vessel 13 or the switch-valve of the usefulness of bleeding is set near it, open this and bleed and the air in the pressurized vessel 13 are expelled to the outside with valve.Can be when the air in having extracted pressurized vessel 13 out, promptly the water level of pressurized vessel 13 rises, and closes above-mentioned bleeding when upper limit switch 30 detects water level and uses valve.Can omit pipe arrangement 33 and valve 35 that exhaust is used like this.
Rise in case accept the supply pressure container 13 interior pressure of carbon dioxide gas, then the water levels in the pressurized vessel 13 will descend gradually.Water level descends in case the 2nd limit switch 28 detects water level, then closes the valve 20 relevant with the supply of carbon dioxide gas and the valve 40 of water shoot 38.Water level begins to rise once more like this.
By the pressure in the pressure warning unit 22 monitor pressures containers 13, when the pressure pressurized vessel 13 in surpasses the value stipulated or the 3rd limit switch 29 and detects water level, turn off the pump 4 of former water supplying pipe 1, also preferably turn off the valve 3 of former water supplying pipe 1 in addition.Finished preparation by above process, become the state that no matter when all can use sterilization water, for example put light blue lamp (not shown) in order to notify.
In above-mentioned ready mode; because inside at the pressurized vessel 13 that is full of with carbon dioxide gas; scatter aqueous sodium hypochlorite solution with micronized state; therefore carbon dioxide gas is dissolved in this aqueous sodium hypochlorite solution; the pH that makes the pH of aqueous sodium hypochlorite solution drop to acidic side adjusts automatically, can generate the sterilization water based on hypochlorous acid like this.And, be slightly acidic owing to carbon dioxide gas is dissolved into the Soda Ash Light 99.2min. that forms in the water, do not worry that therefore the pH of the sterilization water of generation in the pressurized vessel 13 that has been full of carbon dioxide gas drops to the strongly-acid scope.
In addition, sodium bicarbonate is known as the reagent of performance shock absorption, this sodium bicarbonate is added to aqueous sodium hypochlorite solution can make its susceptibility to acid reduce, thereby but the shortcoming that sodium bicarbonate exists continuous release of carbon dioxide gas shock absorption to descend, therefore, must there be regularly or often replenish the operation or the device of sodium bicarbonate.Relative therewith, in an embodiment,, therefore do not need above-mentioned operation or device owing in the pressurized vessel 13 that has been full of carbon dioxide gas, generate sterilization water.
The use pattern:
The above-mentioned ready mode in case be through with, sterilization water generating device switch to the use pattern of adjusting the sterilization water of pH through the dissolving of carbon dioxide gas of all can using any time.If open the manual or motorized valve 39 of sterilization water dispatch tube 37, use the sterilization water by sterilization water dispatch tube 37, then the water levels in the pressurized vessel 13 descend.If the 2nd limit switch 28 detects water level, then open the electric switching valve 3 relevant and open pump 4 once more with former water supplying pipe 1, the aqueous sodium hypochlorite solution that is diluted to normality is supplied to pressurized vessel 13.The concentration that is supplied to the aqueous sodium hypochlorite solution of this pressurized vessel 13 can be adjusted by the addition of the aqueous sodium hypochlorite solution in the head tank 7 that is added into former water through addition portion 10.
Water levels in the pressurized vessel 13 rise, if the 3rd limit switch 29 detects water level, then open the valve 20 relevant with carbon dioxide gas supply-pipe 17, to pressurized vessel 13 supply carbon dioxide gass.Pressurized vessel 13 interior pressure rise like this, rise thereby water level decline owing to press in being somebody's turn to do.Afterwards,, then close with carbon dioxide gas and supply with relevant valve 20, stop pressurized vessel 13 is supplied with carbon dioxide gas if the 2nd limit switch 28 detects water level.The aqueous sodium hypochlorite solution that carbon dioxide gas in the pressurized vessel 13 is injected in the pressurized vessel 13 absorbs, and the pressure in the pressurized vessel 13 slowly descends like this.
By carrying out the supply of the carbon dioxide gas of pressurized vessel 13 repeatedly and stopping, the pressure in the pressurized vessel 13 can being kept necessarily, the water level of sterilization water can also be kept simultaneously necessarily is scope between the 2nd, the 3rd limit switch 28 and 29.If the hypertonia in the pressurized vessel 13, then the dissolving of the carbon dioxide gas in the pressurized vessel 13 increases, and along with the dissolving of the carbon dioxide gas more than necessary, the danger of the pH change of the sterilization water in the pressurized vessel 13 is arranged.
In addition, in this use pattern, if little for example open or close manually or motorized valve 39 reduces the usage quantitys of sterilization water, then compare with the sterilization water of discharging from pressurized vessel 13, the feed rate of aqueous sodium hypochlorite solution that is supplied to pressurized vessel 13 is more, no matter whether open valve 20 and supply with carbon dioxide gas, when following the rising of the water level in the pressurized vessel 13, the pressure in the pressurized vessel 13 also rises.By the interior pressure of pressure warning unit 22 detecting pressure containers 13, when the interior pressure of pressurized vessel 13 surpasses the value of regulation, turn off former water supply pump 4, simultaneously preferred shut-off valve 3 stops pressurized vessel 13 is supplied with aqueous sodium hypochlorite solution.Afterwards, because the use of sterilization water, the water level in the pressurized vessel 13 descends, if the 2nd limit switch 28 detects water level, then open pump 4 once more, open the supply that motorized valve 3 is opened former water once more simultaneously, by this water level in the pressurized vessel 13 is maintained certain limit.That is,, carry out the supply of the aqueous sodium hypochlorite solution of pressurized vessel 13 repeatedly and stop, the water level of the sterilization water in the pressurized vessel 13 is maintained certain limit by user mode according to sterilization water.
Therefore, no matter use a spot of sterilization water continuously, or frequently use and end to use sterilization water repeatedly, as equipment such as impoundment dedicated, also can stably generate sterilization water even without additional.That is, use carbon dioxide gas to generate the effect of playing impoundment dedicated with hypochlorous acid as the pressurized vessel 13 of the sterilization water of main body.
In addition, for example the water level abnormality in the pressurized vessel 13 rises, the limit switch 30 of upper detects water level but interior pressures in the pressurized vessel 13 when surpassing prescribed value, preferably, thus send the (not shown) alerting that sends out a warning of the alarm that has been used to think the dioxide bottle sky and/or point.Certainly be preferably, pressure warning unit 22 detects when pressurized vessel 13 interior pressure anomalies reduce and also gives the alarm.
In the above-described embodiments, when surpassing the pressure of regulation, the pressure in the pressurized vessel 13 closes pump 4, preferably close simultaneously the supply that switch-valve 3 stops former water, as variation, also can between the limit switch 30 of the 3rd limit switch 29 and upper, be provided with and append the limit switch (not shown), in case this limit switch that appends detects water level, then stops pump 4, be preferably simultaneously and close the supply that electric switching valve 3 stops former water.
Flow channel switching valve 9 in that addition portion 10 is provided with for example, can carry out blocked operation at regular intervals, will be back to the head tank 7 from the aqueous sodium hypochlorite solution that head tank 7 extracts with pump.Like this, can remove the bubble that 10 aqueous sodium hypochlorite solution supply passageway, produces from head tank 7 to addition portion.
Preferred not only be adjusted at the amount that addition portion 10 is added into the aqueous sodium hypochlorite solution of former water according to the flow of former water, and can be for adjusting the concentration that its amount changes the aqueous sodium hypochlorite solution that is supplied to pressurized vessel 13.When the operation of the concentration of carrying out this aqueous sodium hypochlorite solution (variation of concentration target value), preferred stop using the sterilization water that generates in the pressurized vessel 13 at the appointed time, and the valve 40 of opening water shoot 38 carries out the automatic operation of device when discarding the sterilization water of pressurized vessel 13.
Below with reference to the accompanying drawing after Fig. 3 each embodiment is described.In addition, be marked with identical reference symbol, omit its explanation for the important document identical with above-mentioned the 1st embodiment, below the characteristic of main each embodiment of explanation.
